DRIVING GEAR FOR CONVERGING SHAFTS.

Application led August 29, 1922. Serial No. 585,067.

T0 all whom t may concern Be it known that we, JOSEPH BAMroRD and CYRIL JOSEPH BAMronD, subjects of the King of Great Britain, residing at St. Marys Mount, Uttoxeter, in the county of Stafford, England, and The Parks, ttoXeter, aforesaid, respectively, have invented certain new and useful Improvements'in Driving Gears for ConvergingShafts; and we do hereby declare the following `to be a full, clear, and exact description of the same.

This invention relates to driving gear for shafts arranged in converging relationship around a centre andhas for its object to provide an improved means for preventing each shaft from making a revolution upon its own centre each time the shafts revolve around theirv common centre.

Shafts arranged in the manner described are used in certain agricultural machines such as swath turners, side delivery rakes, or the like, and may also be used in other Inachines or apparatus. When applied to agricultural machines of the swath turner or side delivery rake type the converging shafts carry tines or rakes and as the shafts rotate about their common centre it is necessary to prevent each shaft from rotating on its own centre in order that the acting ends of thc tines or rakes may always point towards the ground as they are carried around and remain substantially vertical as they approach and leave the ground.

In common with other devices of this class, our apparatus comprises links or cranks which are pivotally connected one to cach of the converging shafts the said links or cranks being connected pivotally each to a stud, all of said studs being .mounted on a rotary carrier which is givenwa rotary more inentaronnd a centre which is eccentric in relation to the centre about which the con-V verging shafts revolve.

One of the` features ol" the present inveni tion consists in. arranging the studs to which thc cranks or links are attached in (.fonvergro' relationship, cach of said studs prcfer-- in abili7 being substantially parallel with the converging shaft with which .it 1s associated.

By employing this arrangement, a more co1n.

pact and convenient apparatus is obtained.

vjecting heads has pivoted thereto at 5 a crank -or link 6. These cranks or links 6 may .be

D Another feature of the present invention 1s to pivot the cranks or links to their studs by pivots which are arranged preferably at right angles to the plane of the crank or link.

A further feature of the present invention is to mount the stud carrier about an eccentric or cam mounted upon a central. driving shaft about which the converging shafts rotate.

As a furtherfeature of the invention, we may mount the tines or rakes upon the outer ends of the converging shafts and substantially in alignment therewith` so that a small and compact controlling head can be used to control tri-nes which diverge to a comparatively large diameter.

lclternativelyJ instead of using an eccentric7 each of the conewise reels may be rotatably mounted on the parallel portions of a non-rotating crank axle, rotary motion being applied to the tine-carrying reel through the medium of a tubular sleeve concentric with the said stationary axle in the known mannerl` Referring to the drawings Figure l is a plan view showing the general arrangement of a swath turner, to which the present invention can be applied.

Figure 2 is a view in side elevation of thc machine.

Figure 3 is a sectional view in side elevation showing' in detail one method of carryin our invention into effect.

*igure 4 is a view in sectional side elevation showing inv detail anothermethod of carrying our invention into practice.

Figure 5 is a sectional view in side elevation showing indetail a further method of carrying our inven ion into practice.

ln the constructions illustrated in the drawings, the converging ohafts l are 5l". ranged with their centres upon an i1naginary cone around. a vcentral driving shaft and the converging shafts vl are mounted in a carrier 3 which is fixed to said shaft.

The inner end of cach converging sha ft .1. adjacent the shaft carrier 3 is provided with a projecting head 4, and each of `these pio arranged substantially at Vright angles to the driving shaft 2 and their other ends are pivotally 'connected at 7 each one to a. stud 8 which is mounted on a. stud carrier 9. These `studs 8 are arranged in converging relationship, Leach stud 8 preferably being parallel with the converging shaft l to which it is connected by a crank or link (i. The pivotal connection between 4each stud and its crank or link, and 5 between each link and its shaft are upon pivots substan tially at right angles to the plane containing the centre lines of the shaft l, the 'link 6 and the stud 8.

The studs 8 are rotatably mounted in the Stud carrier 9 and this stud carrier 9 is mounted upon the periphery of an eccentric 10 (see Figure 3) or crank throuv 17 (see Figures 4 and 5)v mounted upon the driving shaft 2. i`

Alternatively, instead of using an eccentric, the stud carrier 9 may be mounted upcn a cranked stationary aigle. The throiv of 'the eccentric or crank is equal to the eifeo tive lengths of the cranks or links V6.

Instead of using bearin s to carry the studs in the aforesaid stu` carrier 9, reel or carrier may be formed as shown in Figure 4 With pins or arms ll 'prxojecting from its face, of a suitable conevvise disposition, and upon each of the said pins or arms l1 may be mounted a bearing l2 having la suitable pivotal connection 7 for carrying the crank cr link 6 connecting the two controlling reels.

In operation, as the driving shaft 2 revolves and carries with it the carrier 3 of the converging shafts 1 the stud carrier 9 revolves at' the same rate, but thrcugh an eeeentre Orbit Wheh keeps the Creeks o1' links y6 substantially vertical s0 that if the converging shafts l are provided with projecting tines or rakes, the acting ends of these Will point toyvards the gronnd as they are eelfed round, the times remaining et substantially the same inclination to the vel'tCl- If required, when applied to an agricultural meehne', the eeeentre 01 Creek may be provided with a projecting handle, such as 14 provided with a releasable retaining de- Vee 15 by Wheh the eeeentre er Carer-11e may be Secured te etransverse ber 16 unerlthe meehne ee that the 'lateral peeitiee ef the eeevelsie .Shafts Wleeh eer'rv the *lineev .er fakes een eltereel es desired.
